To al@ whom it may concern:

Bc 1t known that I, RICHMOND H. INGER- at Biddeford, in the county ofYork an State of Maine, have invented new and use-V ful Improvements inPicker Mechanism for Looms, of which the following is a specifi'- Thisinvention relates to improvements in looms, relating more articularl tothe pickermechanism by w ich the s uttle is actuated.

The object ofthe invention is to improve the picker mechanism and meansfor actustickused in connection with the or inary form of loon.` Theobjection to the picker stick is well known to those skilled 1n the artand consists in the factthat said picker sticks are constantly breakingbei subjected to a great deal of shock alii? Wear when in use.

The object of the invention is further to provide a picker mechanismwhich will impart a perfectly straight impulse to the shuttle whenthrowing the same across the The object of the invention is further toso construct the mechanism by which ,the shuttleis actuated that whenthe same is thrownand when it is stopped it shall be by a springcushioned picker.

The invention consists in the combination following s )eciiication and'particularly pointed out in tlhe claims thereof.

Referring to the drawings: Figure 1 is a front elevation partly brokenaway and shown in section of a sufficient art of a loom to illustrate myimproved pic er mechanism in connection therewith. Fig. 2 is a sectionalelevation taken on line 2-2 of Fig. 1 looking toward the left in saidfigure. Fig. 3 is 4an enlarfed sectional elevation tionof the pickermechanism with the s uttle engaged b one of the picker slides inreadiness to t irow said shuttle toward the right. Fig. 4 is a sectionalelevation, similar to Fig. 3, illustrating the ,picker slide and aportion of the mechanism by which t of the lay are picker slides 27 and28.

'eye-piece being forked an( it is operated just after the shuttle hasbeen tional elevation on line 3-3 of Fig. 2 illustrating in detail themeans by which the tripper rod is actuated; Fig. 6 is an enlaredsectional elevation taken on line 6-6 gf lFig. 4 looking toward theright in said ure.

gLike numerals refer to like parts throughout the several views of thedrawings.

In .the drawinfrs, 10 is the frame of the loom which maythe of anysuitable and ordinary construction, referably consisting, however, ofside stan( ards 11, 11 joined together by cross ties 12, 13. The lay 14is supported upon arms orlay swords 15, 15 pivoted upon opposite sidesof the frame, upon pivots 16 and 17 (Fig. 1). The lay has the usual reed18 fast thereto and is ro- 'vided with a raceway 19 to guide the s ut'-tle 20 as it passes from one side to the other of lthe loom. The lay isrocked by a link 21 connected to acrank 22 formed upon a shaft 23journaled to rotate in bearings 24 fast to .the frame of the machine.

The driving shaft 23 is rotated by pulleys 26 in the usual manner. Atopposite sides The construction and operation of said slides is the sameexcept that they are`arranged to i propelled across the shed. I Fig. 5is a secoperate upon the shuttle at opposite sides o the shed or at opositeends of the raceway in the lay. liierefore, the following detaileddescri tion of the picker slide 27 will apply equaily well to the pickerslide 28. Referring, therefore, to Fig. 4, it will be seen that thepicker slide 27 consists of two parts, the slide piece or base 29 towhich is fastened the standard 30. The. base 29 slides in ways 31, 31fast to the lay. The standard 30 is provided with a recess to receivethe nose of the shuttle. An eye-piece 33 is fastened to the base 29 b fa screw 34, said istraddling an ear 35 formed upon said base throughwhich the screw 34 projects. The eye-piece 33 is provided with ascrew-thread to receive and hold one end of a tension spring 36. 'lheopposite end of said spring 36 is fastened to a rod 37, the opposite endof said rod 37 being fastened to another tension spring 38 which, inturn, is fastened at its rlght hand end (Fig. 1) to the picker slide 28by means of another eye-piece 33 andscrew. An interlmittentreciprocatory; motion Iis imparted to the rod'37 by a belt 39,' whichmay be of Wire, leather, or any suitable flexible material, The' centralportion of the belt 39 e extends longitudinally ofthe lay and has'fastened thereto a buffer 40 which is clamped by screws 41't`o the -belt39 and extends upwardly from said ,belt (Fig. ),v terminating in acylindrical sleeve 42 which i's fast to the rod 37. Said rod 37 andbuffer 40 thus con* stitute in effect', a singlev member movable Y- -lo'tudinallybf the-lay.

VSaid -shipper rod has fastenedthereto two collars 45 and46 and en- I* gages `at opposite endsthereoflocking de- `vices adapted to hold r the picker slides againstmevement, as hereinafter described.. Said 'lockingdevices consist ofangle levers 47 and 48, the lever 47 having a hole therein through whichthe left hand end of the rod 44 projects (Figs. 1, 3and4).l

Nuts 49 and 50 have screw-threaded engagement with` op osite ends,respectively, Alof the rod V44. lars 51, 52 looseupon the' rod 44 bearagainst the trip le tively. Spiralspri S53 and 54 bear'at one endagainst the colarev 51 and 52, respectively, -and at the 'oppositeendagainst `clamp collars 55 and /56,` respectively. Referring toFigs.-*/f/and 2 it will be seen that thebeltor rOpe/'SQis fastened latone end thereof to a cana"` to afbracket v59'fast tdpthe frame., Saidjlever '57 vis provided with a cam rolll 60 which Ibears against thecamv61 fast to a I lay sword. llirom the pulley 66 the' belt' 39 extendslongitudinally of the lay to another:

' The general opera-tion of my improved picker mechanism for looms visas follows:

Assuming theI arts to be in the positions illustrated in lgs. 1, 2 and 3and `that' the shed is fopen, as indicated in dotted lines .(Fig. 2),the belt 39 will be ymoved by its cam vers 47 and 48, respecver -57pivoted, at 58 justing nuts 76, .77. ceived by the'picker slide 28,which slide is held and the blow of the shuttle thereon cushf .againstacam 61 fast to the shaft.

levers toward the right (Fig. 1), carrying y vwith it the buffer 40 androd 37 thus through the spring 36 moving the picker slide 2.7 toward theright until the shoulder 69 upon the,

lower face of the base 29 abuts against the horizontal arm of thetripper lever 47, arresting further motion of the picker slide ,27,

but the movement of the rod 37 and belt 39 toward the right continues,thus extending the spring 36, one end of which, it will be remembered,is fastened to the-rod 37 and the other to the eye-piece 33. The spring36 will be extended until the buffer 40 engages the collar 46 upon theshipper rod 44, when said shipper rod will be moved toward the rightfrom the position shown inFigs. 3 and\\5 'to that shown in Fig. `4,tliusrocking the tripper lever 47 and disengaging the picker `slide 27which is immediately moved toward the right from the Vposition shown inFig.v 3 to that shown in Fig.' 4.- The shuttle 2013 thus thrown from thepicker slide 27 to the picker slide 28 through the shed and performs theoperation of carryingthe shuttle thread between. the warp'lthreads inthe manner well knownuto those skilled in this art. Motion of the pickerslide 27 toward the right is arrested by a stoplate' 7 O which. ispreferably provided with a' eather facing 71, and is fasto spiralsprings'72,72 (Figs.-3, 4 and 6). The

spiral springs72'are-each fastened at one end -teiied at ,opposite sidesthereof, respectively,

to thejst'op-plate 7,0; and at the opposite end to a screw-threadedholder 73 which is -advvjustably fastened `to an extension 74 of` thelay frame by a screw The shuttle 20 is \`re threaded rod 75 and adionedby `the spring 38 which is attached to the right hand end of the'lrod37, as hereinbe fore described. Simultaneously with the unlos lockingof the" picker slidev 27 by the tipping ofthe tripper lever 47, thetripper lever 48 is tiIppedint-o the position shown in dotted lines ig.1), the same corresponding in vposition lck the pickerslide 28 againstmbv'ement to- Ward theleft whenthe motion of the belt 39 7 is reversedin the same manner as the tripper lever 47 locked Athe slide 27 againstmovement toward the right during the first part ofthe movement of saidbelt'an'd the rod`37 toward-the ri lht, as hereinbefore described,preparatory to the unlocking of thesame and subsequent propulsion ofthe' shuttle across theshed.

-sai lay,

,'locksfadapted to alternately lock and releasf throwing the shuttlefrom the right to the left is exactly the -same as hereinbeforedescribed in relation to thel releasing of the, picker' slide 27 andthrowing `the shuttle toward the right. As the belt moves toward theleft the rod 37 is moved by said belt and thebuffer .40 until all of thetension is removed from the spring 36, whereupon said spring acts topush the picker slide 27 toward position illustrated in Fig. 4 3. At thelatter part of the movement oi3 the picker slide 28 toward the left thebuffer 40 will engage the collar and move the rod 44 toward the left,rocking the tripper lever 47 vfrom the position shown in Fig. `4 intothe position shown in Fig.` 5., and during the latter part of the1movement of the picker slide 27 toward the left the horizontal arm ofthe tripper lever 47 will be moved upwardly against the under s ide ofthe eye-piece 33 in readiness to engage, the shoulder 69, ashereinbefore described.
